FAQ’s

Does chlorine make your eyes sting?

It is very rare for chlorine granules to cause your eyes to sting. Having an incorrect pH level causes eye sting and skin irritation.

Can I sprinkle the granules directly into my spa water?

Yes as the water is warm and a spa has a smaller volume than a pool the granules will dissolve when applied directly to the spa water. Simply turn your spa pumps on, sprinkle in and let it circulate to dissolve evenly. However with pools we recommend you pre-dissolve in a clean plastic bucket filled with pool water.

Will this chlorine damage my spa cover?

To prevent chlorine marks on your cover you should ensure your hot tub cover is left off for 5-10 mins after dosing to prevent any deterioration.

How do I measure the amount of chlorine in my spa?

Use chlorine test strips to measure the Free Chlorine level in your hot tub. The idea range is 3-5ppm.

How much chlorine granules do I need to add to a hot tub?

For a hot tub with 1,000 Litres by 1ppm, add 2g of chlorine granules. See the directions for use tab for full instructions.

Are Chlorine Granules or Tablets better?
